Specification of Letters Patent.

Patented May 16, 1911.

Application filed October 3, 1910. Serial No. 585,071.

To all whom it may concern:

Be it known that I, JOHN A. DEADY, a citizen of the United States,residing at Milldale, in the county of Hartford and State ofConnecticut, have invented a new and useful Improvement inTrolley-WVheels; and I do hereby declare the following, when taken inconnection with the accompanying drawings and the letters of referencemarked thereon, to be a full, clear, and exact description of the same,and which said drawings constitute part of this specification, andrepresent, in

Figure 1 a side view of a trolley wheel constructed in accordance withmy invention, a portion of the wheel being broken away showing theoil-defiecting partitions within the oil-chamber of the wheel. Fig. 2 aview of the wheel in vertical section on the line a-b of Fig. 1. Fig. 3a' similar view of the wheel in horizontal section on the line ccl ofFig. 1. Fig. 4; a broken view of the wheel in vertical section on theline ab of Fig. 1 but with the bushing removed. Fig. 5 a plan View ofthe bushing.

My invention relates to an improvement in trolley-wheels, the objectbeing to provide, at a low cost for manufacture, a simple, convenientand durable wheel composed of few parts and constructed with particularreference to guaranteeing a liberal and uniform oiling of the arbor.

Vith these ends in view my invention consists in a trolley-wheel havingcertain details of construction as will be hereinafter de scribed andpointed out in the claim.

In carrying out my invention, I employ a bushing 2 formed of bronze orother metal, and having a central longitudinal arbor-hole 3 for thereception of the arbor 4. The said bushing is permanently mounted in thecenter of the trolley-wheel 5, being supported at its ends incorresponding openings 6 located opposite each other in the hubs 7 ofthe wheel the central portion of which is cored out to form a concentricoil-chamber 8 which entirely surrounds the unsupported central portionof the bushing as clearly shown in Figs. 2 and 3. For leading the oildirectly from the chamber 8 to the arbor 4 passing through the hole 3,the bushing is formed with a centrally arranged radial port or opening 9leading from its periphery into the arbor-hole 8. For leading oil fromthe chamber 8 to points outside of the wheel so as to lubricate thebearing of the flat outer faces of the hubs 7 upon the washers 10, Iform the bushing 2 with shallow channels 11 leading in oppositedirections from the ends of its radial port 9, and terminating againstthe inner faces of the washers 10 as clearly shown in Fig. 3. Now toinsure the delivery of the oil in the chamber 8 to the radial port 9 andchannels 11 of the bushing, I form two oil-deflecting ribs 12 in thechamber 8, these ribs being cast integral with the trolleywheel 5,extending in opposite directions and located relatively near each otheras shown in Fig. 1, itbeing designed that the bushing 2 shall bepositioned in the holes 6 in the hubs 7 so that the port 9 and channels11 of the bushing shall lie between the two ribs 12. It will beunderstood that the tendency of centrifugal force to carry the oil inthe chamber 8 to the outer periphery thereof, and away from the bushing,will be defeated by the ribs 12 which will throw the oil inward uponthat portion of the bushing containing the port 9 and channels 11.

I claim The combination with a trolleywheel formed with a concentricoil-chamber having oil-deflecting ribs extending into it from oppositedirections and located relatively near together, of a bushing mounted inthe wheel, passing through the center of the said oilchamber and formedwith a radial port for lubricating the arbor, and with longitudinaloil-channels for lubricating the outer bearings of the said wheel, thesaid bushing being positioned with its port and channels between theoil-deflecting ribs aforesaid.

In testimony whereof, I have signed this specification in the presenceof two subscribing witnesses.

JOHN A. DEADY.
